ABSTRACT:
In an internal-combustion engine, when the rotational speed of the engine is lower than a predetermined value, the amount of fuel to be injected into the engine is determined by the coolant temperature thereof. The amount of fuel is also changed in accordance with the change of the opening of a throttle valve provided in an intake-air passage of the engine.
